Gentlemen
I thought you might be interested in the following:
I just installed CentOS 5 on a computer (kernel-2.6.18-8.1.4.el5.i686) . On
boot, I get an error message,
related to 2 SATA disks. These errors did NOT appear on version 4.4
(kernel-smp-2.6.9-42.EL.i586) with the
EXACT same hardwar

Hi,
.
We want to see and erase hpa on FC7 for SATA hdd.
So added libata option on Grub and modprobe.conf.
We can see the HPA detection message on dmesg and
/var/log/messages.
But the setmax.c doesn't work to change max address.
Also "dd" command covering hpa are doesn't work
anymore. The process ne

This is generally a bad practice to guess protocol based on opcode.
What if the code will have to handle a vendor unique command (or some
other command not yet known to it but known to issuer)?
Agreed -- we simply cannot rely on guessing protocol from opcode, we

It looks like the ATA passthru commands contain more information than
what libata needs to execute a command.
e.g. protocol number:
libata could possibly infer the protocol from the command opcode.
e.g. multi_count:
libata caches dev->multi_count. Passing multi_co

Hello,
Could anybody point me to a driver for the Silicon
Image SATA 3124 controller running under linux 2.4.
I am currently using a microblaze core under uClinux
And therefore cannot use the driver for the 2.6 kernel.
If no driver is available could somebody give me some advice
As to what is the
Hi Tejun,
Okay, there was a bug in link speed limit logic. That's probably why
speed down to 1.5Gbps didn't kick in. The attached patch contains the
fix and hack to force 1.5Gbps. Please give it a shot.
thanks a lot for your patch, it seems to work, at least better than
without patch. :-)
